Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

So with these non OEM fuses, does anyone think it would be doable to convert the fuses without screw terminals into fuses with screw terminals by soldering the fuse to some copper fashioned into screw terminals and soldering the fuse to the copper?

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Electronpusher: When I ran into problems getting the original 20 amp fuse, I bought the 10x38 fuse type that you showed in your last post. To be able to use it, I also bought a DIN fuse holder, and ran wires from the fuse holder with small ring terminals that would screw down to the original two sc...

As for the fuse, would this work? https://au.rs-online.com/web/p/products/7686125/?grossPrice=Y&cm_mmc=AU-PLA-DS3A-_-google-_-PLA_AU_EN_Fuses_Sockets_And_Circuit_Breakers-_-Fuses%7CCartridge_Fuses-_-PRODUCT+GROUP&matchtype=&pla-392408123959&gclid=CjwKCAjwxILdBRBqEiwAHL2R83h1tofZAmpY...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

On the second OBC that I just finished working on, I've been told that the charging failed during a night that there was a storm and heavy rain. This could point towards a blackout, brownout, or power surge as the source of the falult. Just playing catch up on this thread, haven't had a chance to l...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Hi ChristopheFR, It sounds different because your symptoms are different to the other charger failures, why that is we simply do not know at this point. While I see merit in the Aux Battery theory, I am not completely convinced it is the Aux Battery just yet, since we had our Aux Battery replaced ab...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

I cannot collaborate this, as it is only the sellers word, but when we bought the car, he said that he had the Aux Battery replaced because the car would not power up. So the battery is supposed to be about 1 year 4 months old, the battery indicates it is good, but the battery is rather tiny. So pos...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Interesting discussion regarding the Aux Battery possibly being to blame for the MCU Fuse/Snubber Caps issue. Taking that into consideration, we have a battery that is rather small compared to the size of the battery box, and hence I would like to swap it out before I put back in repaired components...

Make that three, ours has failed exactly the same way, MCU Fuse and Snubber Caps blown.
